Synopsis: War has come in this sequel to the best-selling novel THE LOST LEVEL. The snake-like Anunnaki have always been a blight for the people living in the hidden dimension known as the Lost Level, but now, the denizens are fighting back. After their community is decimated and their loved ones are enslaved in the aftermath of a devastating Anunnaki attack, Aaron Pace leads a diverse group of warriors — including the bow-woman Tolia, the mighty Karenk, a baby Triceratops, and a time-displaced Ambrose Bierce — on a trek through primordial jungles, dark forests, and a sun-blasted desert while battling pterodactyls, man-eating worms, and other dangers. Can their small band lay siege to the Anunnaki city and rescue their friends, or will they suffer the same cruel fate so many others have before them? Find out in Brian Keene’s RETURN TO THE LOST LEVEL.
